This experiment comprises one free-running hind-cast simulation (1950-2019) with EMAC at T42L90MA resolution under the CCMI-2022 refD1 protocol, see SPARC, 2021: SPARC Newsletter No. 57, July 2021, 39 pp., available at http://www.aparc-climate.org/publications/newsletter. The 'ECHAM5 (5.3.02)' files contain variables describing the physical / meteorological state of the atmosphere as simulated by the ECHAM5 General Circulation Model and the 'tr_Ox_HOx' files contain chemical species related to ozone. The Modular Earth Submodel System (MESSy - version is documented in the file header) is an integrated software framework for the assembly of Earth System Models (ESMs). MESSy is a multi-institutional project. "R" is short for "Ref" (=reference) according to the experiment protocols (in contrast to "S" for sensitivity). "C" and "D" denote the experiments of the first (CCMI-1) and second (CCMI-2022) project phase, respectively. Hind-cast simulations are labelled "1", and combined hind-cast and projection simulations are labelled "2". "SD" denotes "specified dynamics" simulations.

The 'ECHAM5 (5.3.02)' files contain variables describing the physical / meteorological state of the atmosphere as simulated by the ECHAM5 General Circulation Model and the 'tr_Ox_HOx' files contain chemical species related to ozone. The specified dynamics has been achieved by nudging (Newtonian relaxation) of EMAC towards ECMWF ERA-5 reanalysis data.

The data represent monthly average values of pre-industrial climate simulation. Here, for the year 1860, concentrations of well mixed greenhouse gases (CO2, CH4, N2O) were prescribed. Ocean data (MPI-OM) are available within this experiment, they are stored in EXTRA FORMAT. Datasets with higher resolution (6 hour mean) are also available. As the boundary conditions are not time dependent, the time access is arbitrary. Technical data to this experiment: The experiment is using ECHAM5.2.02 coupled to MPI-OM Vers.1.0 GR1.5L40 and was run on a NEC-SX6(hurrikan). The output from the model run: hurrikan.dkrz.de:/ut/3/m214002/EXP500/run520
